NOTE:
As the camshaft bracket is manufactured with the cylinder head, it is impossible to replace only the cam-
shaft bracket.
Camshaft End Play
●Set the dial gauge to the front end of the camshaft. Measure the
end play by moving the camshaft in the direction of the axle.

INSPECTION
●When the camshaft or parts in connection with valves are
removed or replaced, and a malfunction has occurred (poor
starting, idling, or other malfunction) due to the misadjustment of
the valve clearance, inspect as follows.
●Inspect and adjust when the engine is cool (at normal tempera-
ture).
●Be careful of the intake and exhaust valve arrangement. The
valve arrangement is different from that in a normal engine.
NOTE:
The camshafts have, alternately, either an intake valve or an
exhaust valve.(Refer to illustration)
1. Drain engine coolant. Refer to CO-29, "
Changing Engine Coolant" .
2. Remove charge air cooler. Refer to EM-122, "
Removal and Installation" .
3. Remove air duct and air inlet pipe. Refer to EM-120, "
Removal and Installation" .
4. Remove rocker cover. Refer to EM-156, "
Removal and Installation" .
5. Remove vacuum pump. Refer to EM-139, "
Removal and Installation" .
6. Remove injection tube and fuel injector. Refer to EM-144, "
Removal and Installation" .
7. Remove secondary timing chain. Refer to EM-167, "
Removal and Installation"
Check valve clearance while engine is cold and not running.
8. Set the No. 1 piston to TDC on its compression stroke.
●Turn crankshaft pulley clockwise so that the knock pin on
camshaft LH faces straight above. (No position indicator, etc.
is provided on the crankshaft pulley.)
9. Put an alignment mark with paint, etc. on the crankshaft pulley
and on the oil pump as an angle indicator.
10. While referring to the figure, measure the valve clearance
marked in the table below.
●The injection order is 1-3-4-2.

●Remove the adjusting shim for parts which are outside the spec-
ified valve clearance.
1. Remove the spill tube. Refer to EM-144, "
Removal and Installa-
tion" .
2. Extract the engine oil on the upper side of the cylinder head (for
the air blowing in step 7).
3. Rotate the crankshaft to face the camshaft for adjusting shims
that are to be removed upward.
4. Grip the camshaft with camshaft pliers, them using the camshaft
as a support point, push the adjusting shim downward to com-
press the valve spring.
CAUTION:
Do not damage the camshaft, cylinder head and the outer
circumference of the valve lifter.Valve clearance (Cold):
Standard:
Intake : 0.24 - 0.32 mm (0.0094 - 0.0126 in)

5. With the valve spring in a compressed state, remove the cam-
shaft pliers by securely setting the outer circumference of the
valve lifter with the end of the lifter stopper.
●Hold the lifter stopper by hand until the shim is removed.
CAUTION:
Do not retrieve the camshaft pliers forcefully, as the cam-
shaft will be damaged.
6. Move the rounded hole of the adjusting shim to the front with a
very thin screwdriver or like that.
●When the adjusting shim on the valve lifter will not rotate
smoothly, restart from step 4 to release the end of the lifter
stopper from touching the adjusting shim.
7. Remove the adjusting shim from the valve lifter by blowing air
through the rounded hole of the shim with an air gun.
CAUTION:
To prevent any remaining engine oil from being blown
around, thoroughly wipe the area clean and wear protective
goggles.
8. Remove the adjusting shim by using a magnetic hand.
9. Measure the thickness of the adjusting shim using a micrometer.
●Measure near the center of the shim (the part that touches the
camshaft).
10. Select the new adjusting shim from the following methods.
SBIA0185E

Calculation method of the adjusting shim thickness:
R = Thickness of removed shim
N = Thickness of new shim
M = Measured valve clearance
Intake
N = R + [M - 0.28 mm (0.0010 in)]
Exhaust
N = R + [M - 0.30 mm (0.0118 in)]

lifter.
12. Compress the valve spring using the camshaft pliers and
remove the lifter stopper.
13. Rotate the crankshaft 2 to 3 turns by hand.
